The rugby star revealed on Players Voice on Monday night he never meant to hurt anyone with his Instagram comment, but he could never shy away from who he is.
Rugby Australia CEO Raelene Castle speaks to media during a press conference on rugby player Israel Folau's use of social media.
Folau also hit out at Rugby Australia chief Raelene Castle for her comments about him after he was summoned to a meeting with the governing body, which has an inclusion policy to stop discrimination, over his anti-gay remarks.
Folau used a Players' Voice column to further voice his strong religious beliefs after posting on Instagram two weeks ago that gays were headed for "HELL" unless they repent their sins and turn to God.
"After we'd all talked, I told Raelene if she felt the situation had become untenable - that I was hurting Rugby Australia, its sponsors and the Australian rugby community to such a degree that things couldn't be worked through - I would walk away from my contract, immediately", said Folau, who is off contract at the end of the year.
Last year, Folau prompted disagreement within the Australia team after he posted on Twitter about his opposition to same-sex marriage in the build-up to the country's vote on the issue.
He said for him it was "not about money or bargaining power or contracts", but proclaimed his faith was more important than his career.
"But I would like to explain to you what I believe in, how I arrived at these beliefs and why I will not compromise my faith in Jesus Christ, which is the cornerstone of every single thing in my life".
He wrote: "Since my social media posts were publicised, it has been suggested that I am homophobic and bigoted and that I have a problem with gay people".
He has made 62 appearances for Australia, having initially started out as a rugby league player.
"This could not be further from the truth. In my heart, I know I do not have any phobia towards anyone".
When asked if Folau understood the pain his comments could cause, Castle replied: "Yes, and I think Israel has acknowledged that maybe he could have put a positive spin on that same message and done it in a more respectful way". He might be determined to maintain his course and doesn't want to hear what you have to say.
"No man or woman is different from another - if you sin, which we all do, and do not repent and seek forgiveness, you will not inherit the kingdom of God". But if you don't tell him the truth, as unpopular as it might be, he is going to fall into that hole.
